YARN GUIDE FOR- WINDING MACHINES.

Application filed November 6, 1924. Serial No. 748,278.

T 0 all whom it may concern:

Be it known that I, Lnwrs T. HOUGHTON, a citizen of the United States, residing at Worcester, in the county of Vvorcester and State of Massachusetts, have invented a new and useful Yarn Guide for l/Vinding Machines, of which the following is a specification.

This invention relates to a device for guiding thread or yarn to a package on which it is to be wound and is particularly adapted for use on machines building up a tube or package having ends at right angles to the length thereof so as not to require any sup port at the end. .In winding these tubes or packages it is necessary that the guide move along the same in contact with the yarn that has been laid on the package and it has been the practice heretofore to provide an eye having a V-shaped groove which engages the package at the point at which the yarn passes to the package over a metallic surface. Ordinarily the yarn approaches the package at substantially a right angle to the surface of the package, that is radially, and makes a sharp angle or bend at this point which raises the fibers on the yarn as it passes over an angle and therefore produces roughness. These fibers once raised are not laid back on the yarn in the winding of the tube and therefore the product is not as smooth as it might be.

Another disadvantage of the old type of guide eye is that as the yarn passes over the metallic surface at the point at which it is located on the package it wears a groove in the eye and this groove destroys the usefulness of the eye in a very short time, although they are hardened and every pre caution is takemto reduce the wear. The principal objects of this invention are to provide a construction of yarn guide which will avoid the wear of the yarn on the surface of the guide that engages or supports the package and to provide means whereby the yarn will not form any acute angle or, in fact, any material angle as it passes to the surface of the yarn package.

The first object is accomplished by providing a guide which has no bottom surface in contact with which the yarncan pass to the yarn package but instead has a groove in which it is retained by the sides of the guide and which has no bottom. The second object is also accomplished by this construction as it permits the yarn to come against the yarn package almost on a tangent line and therefore does not cause the fibers of the yarn to be raised on the convex side as it passes to the package.

tachable plate on the guide holder where it rubs across the traverse frame so that it can be replaced when worn without necessitating any wear on the holder itself.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Fig. 1 is an end view of the traverse mechanism and tube support for a winding machine with a holder and yarn guide constructed in accordance with this invention;

F g. 2 is a front elevation of the same;

Fig. 3 is a view of the yarn guide taken from the opposite side from that shown in Fig. 1; and

Fig. 4 is a sectional view on the line 4et of Fig. 3.

I have shown the invention as applied to the usual traversing mechanism which moves the thread or yarn back and forth while winding it on a rotary tube T or the like to form the thread or yarn package P. I have shown the usual traverse rod 10 at the bottom of the traverse frame 11. The holder 12 is fixed to the rod by a screw 13. These parts are shown as of the usual construction. I have shown the holder as provided with a detachable plate 15 formed of sheet metal and having two side flanges 16 for engaging the sides of the holder and keeping it in position. It is also provided with two parallel projections 17 which pass through perforations 18 in the holder to secure it in position. This easily replaceable plate slides along the traverse frame 11 and receives the wear which otherwise would wear out the holder and necessitate its replacement.

At the top the holder 12 which is formed of sheet metal is bent around at right angles to its plane to provide a supporting and locating flange 20, as shown in Fig.3. This flange being integral with the holder constitutes a means for locating the yarn guide. This yarn guide comprises a sheet metal plate 21 having a flange 22 around three sides abut-ting against the edges of the flange 20 so as to constitute a locating means.

T he plate 21 is provided with a pair of Another ob ect of the lnventlon is to provide a decated so that'the stud 23 which is the final gui le over which the yarn passes to the package 'l? is locatedas near it as is convenient.

against it all the time and the holder 12:

moves-"out as the'package grows and yet the yarn always comes to th'epackage 'on a2tangent. This *isanqhhportant point because as the yarn is laid-ion the package; it is movingin a straightpatlr and therefore the" fibers are not rougl'i'ened up on its surfacejust a that point as they have been heretofore. This results in a very much-smoother product than has been obtained before and enhances its value materially. In the-old form'with which I am familiar the yarn usually is deflected-so-that itpasses to the" package radially or nearly so. My object isto prevent on reduce this deflectionso that the yarngoes to thepaekageat'an acute: angle" or tangent. Another point to be ob served iis thatthe yarn bears against ;no metallic su'rface'afterit leaves the'stud'23. lVhere'it is pressed against the yarn packaget-h'ere is no metallic surface-behind it and "therefore there is no surface at that point to be worn by the passage oftheyarn: over it and the pressure of the yarn against it or between it and the package. The yarn is entirely free from metallic surfaces at the.

These it ispassed through a plate 26 on the other side as shown in Fig. 1

This'with the stud 23 fixes these three flangesor "plates 20, 21 and 26 together. The "latter-are 'space'd'ap'art by 1-11 28 on the bolt or: screw 27. This ier is large enough so'that-they are point where it'is wound on-the package. Nevertheless "the two plates 21 and 26 retain it in position between them no matter what its angle and keep it from moving sidewise. 7

If there is a little wear on the convex sur-- faces of the flanges 22 and 29 that Wear from the top; down so that the wear is uniform along these surfaces and tends to keep them smooth instead of grooving them, but there is'vcry little wearuponathem because they do not press the thread against the package: Of course the wearon the stud 23 cannot be avoidedbut that studzcanrabev loosened and turned only part way around to restore it to its original surface and when it is worn all around the stud'candae removed and replaced at very little cost. The same is true of course of :thex-piate-ld which has been described;v

This invention is suitable for thread or yarn and-I do not wish to be-limitedto either 'to the exclusion of @theother.

Although- I have illustrated and. described onl y a si-ngle form of-the invention I am 90 aware of the fact that-unodifications can be made therein by anyperson skilled inthe artwithout departing. from the spiritaand scope of the invention as: expressed in the claims;

Therefore I-do not wish to be limited to the details of construction herein shown: and described, but-what I do claim is 1. The combination with? ,atraverse. frame :and a guide: holder *movab le along'the frame; of a sheet metal .bearing'plate'canried by the holder near-thetop at a poin-t-to .engage theframeto receivethe wearroifthe Zho'lder against the frame said plate .hf avi'ng integral side flanges detaehablyholding. it 195 on said holder.

2. A yarn guide for tubing or winding thread having-two supports at its sides-in the same planearran ged to contactwith the yarn tube or package, two parallel wallsextending backwardly from said supports, and being without any bottom support for the yarn where it contacts with the tube or package.

3.- A yarn guide for b uildingzupa yarn package by tubing or winding having. two parallel studs; one constituting, means for receiving the yarn, and theother means for guiding it to the package in a zpath tangent-i to the surface thereof throughout the'entire operatio-niof winding, and means for keeping. said guiding -1n-eansat a constant distance from the surface of the: package as the -latter increases in size.

4L- A-yarn guide for the purpose descnibed comprising 'a stud for receiving-the yarn and a pair of parallel side walls spaced about atright'an-glesto the axisrof the stud adapted to engage the yarn package, the guide having no bottombearing back-of the point discharge to deflect the yarn from a straight path from its support on the stud to the tube or package and thus permitting the yarn to have a path from the stud substantially tangent to the tube or package.

A yarn guide for the purpose described comprising a pair of parallel side walls spaced apart adapted to engage the yarn package, a bearing for the yarn between said plates at a material distance back of the point of engagement with the yarn package, the guide having no bottom bearing back of the point of discharge to deflect the yarn from a straight path between said bearing and the surface of the package, thus permitting the yarn to have a path tangent to the tube or package.

6. A yarn guide comprising two plates spaced apart to form a yarn receiving groove between them, a. yarn support extending across the space between the plates over which the yarn passes, said guide being adapted to press against the package being wound and said support being spaced from the package, whereby the yarn will pass directly from the yarn support to the package and will not be deflected out of its straight path between them.

7. A yarn guide comprising two parallel plates spaced apart and having edge flanges around them providing'rounded corners for convenience in threading and constituting means for pressing against the package, and yarn support between the plates back of said flanges and constituting the sole means for supporting the yarn between said plates.

8. As an article of manufacture, a yarn guide for the purpose described having no bottom bearing at the point at which the yarn contacts with the tube or package to deflect the thread or yarn from a straight path as it passes to the tube or package and having side supports bearing against the tube orpackage for insuring the spacing of the yarn in proper position during the traverse motion.

In testimony whereof I have hereunto affixed my signature.
